Title: Device and method for detecting wavelength of light
Inventor: MATSUZAKI ICHIRO
IPC: G01J3/36
Filed: 1989-03-27
Abstract: PURPOSE:To measure the wavelength of light subjected to pulse modulation or AC modulation by detecting the converged position of the light diffracted by a diffraction grating by means of a semiconductor position detecting element and giving a sampling signal to an output signal so that a detection signal may be found. CONSTITUTION:The detecting light L1 from a semiconductor laser light source 30 is made into the collimated beam of light by a convex lens 3 and spectrally divided to the respective wavelengths by the transmission type diffraction grating 4 so as to obtain the diffracted light L4, which is converged by a convex lens 5, and the converged light L5 is detected by the semiconductor position detecting element(PSD) 6. The output signal S1(S2) from both ends of the PSD 6 is amplified by an amplification circuit 11(12) and changed to a differentially amplified signal S5(S6) where a signal corresponding to a noise is removed by a differential amplification circuit 13(14). Then, it is made a peak hold signal S7(S8) by a peak hold circuit 15(16) and converted to an addition signal S9 or a subtraction signal S10 by an addition circuit 17 or a subtraction circuit 18. The detection signal S11 obtained by a division circuit 19 is compared with a comparison signal S12 shown by a ROM 20 in a comparison circuit 22, so that a signal S13 showing the wavelength of the detecting light L1 is found.

Title: Floppy disk driving device
Inventor: HAMA HISAAKI
IPC: G11B21/12
Filed: 1986-04-02
Abstract: PURPOSE:To reduce a load and a shock to be inflicted on a disk at the time of starting by providing a cam that moves an upper carriage vertically in a part other than the recording area of the disk and moving and controlling upper and lower carriages to the cam part when a motor signal is turned off. CONSTITUTION:In the stopping state of a disk driving motor, upper and lower carriages 3, 10 are positioned in the outer periphery side from the outermost peripheral recording and reproducing track of a disk 1, and an up and down pin 6 of the carriage 3 runs on the upper part of a cam 7a provided at the tip of a holder 7, and an upper magnetic head 2 made not to touch the disk 1 or not subjected to force of a head load spring 4. In the state where reading and writing are possible, the pin 6 of the carriage 3 is disengaged from the cam 7a and goes to a head loading state. Accordingly, the head is not in contact with the disk, and therefore, starting torque is small and current consumption is also small. When the carriage 3 moves to an objective track, it goes down along the cam, and accordingly, a shock to be inflicted on the disk is lessened.

IPC: F02N15/02
Filed: 1984-04-18
Abstract: PURPOSE:To improve operation efficiency of a starter motor by interposing an eccentric gear mechanism in the transmission system of a starter motor and operating an engine with a relatively large gear ratio on the top dead center side, and with a relatively small gear ratio on the bottom dead center side. CONSTITUTION:When an engine 1 is to be started, the output of a starter motor 2 is introduced to the engine 1 through a reduction gear train 7, one-way clutch 8, and an eccentric hear mechanism 10.

Abstract: PURPOSE:To prevent device characteristics from being fluctuated by a temp. change by providing a conductive material for joining 1st and 2nd dielectric substrates and joining the 1st and 2nd ferroelectric substrates via the conductive material in such a manner that the sponteneous polarization directions are reversed from each other. CONSTITUTION:Electrodes 5 which impress electric fields to waveguides 4 diffused with Ti are formed via an SiO2 buffer layer 3 on the dielectric substrate (Z plate LiNbO3 substrate) 1 formed with the waveguides 4 on the face (-Z face) coinciding with the spontaneous polarization direction. Further, the dielectric substrate 2 the rear face of which is the -Z face and has the same thickness as the thickness of the substrate 1 is stuck to the rear face of the substrate 1 via the conductive layer 6. Since the spontaneous polarization directions of the substrate 1 and 2 are reversed according to this constitution, these directions are negated by each other and the pyroelectricity is eventually prevented. The pyroelectricity is prevented even if the waveguides are formed by using the dielectric substrate having the pyroelectric effect. The optical waveguide device which is not fluctuated in the characteristics by a temp. fluctuation, etc., is thus obtd.

Abstract: PURPOSE:To obtain an arbitrary pulse width between entire regions including the maximum and minimum values as a pulse output, by changing a reference voltage of two comparators in cascade connection toward opposite directions related with each other. CONSTITUTION:Two comparators 11 and 12 are operated in cascade, and a reference voltage Vx of the comparator 11 and a reference voltage of the comparator 12 are set by fixed resistors R1-R4 and a variable resistor Rv.
